7.10. Unsupported Reconfiguration Modes

The following reconfiguration modes are not supported:
  • Switching between a receiver-only channel and a transmitter-only channel
  • Switching between bonded to non-bonded mode or bonded mode with different xN lanes count (for example, switching from bonded x2 to bonded x4)
  • Switching between one PHY IP to another PHY IP (for example Deterministic Latency PHY IP to Custom PHY IP)
  • TX PLL reconfiguration is not supported if the TX PLL is connected to bonded channels

You can achieve PHY to PHY IP reconfiguration only if you use the Native PHY IP to configure your transceiver. For example, if you use the Native PHY IP to configure the SDI mode and a custom proprietary IP mode (also configured using Native PHY IP), you can reconfigure these two modes within the Native PHY IP. The switching refers to enabling and disabling the PCS sub-blocks for both SDI and the custom proprietary IP mode.
